QIDI Max4 Combo FDM 3D Printer

The QIDI Max4 is the ultimate professional 3D printer, combining industrial-grade precision, absolute stability, and compatibility with advanced high-performance filaments. Its 390×390×340 mm build volume allows printing prototypes, functional parts, and complex models without compromising quality. It's the perfect choice for engineers, designers, makers, and companies seeking high-volume, high-accuracy professional 3D printing.

Professional 3D Printing with Industrial Temperature Control

The printer features a heated chamber up to 65°C and a ultra-uniform heated bed, providing perfect adhesion, thermal stability, and precise layers. Its active air system and anti-clog extruders reduce blockages by up to 90%, enabling the use of filaments such as PLA, ABS, PETG, PPS-CF, and carbon fiber composite filaments. Each print achieves professional, industrial-level quality, surpassing standard professional 3D printers.

The QIDI MAX4 provides enhanced temperature control thanks to its active air cooling system, which, combined with the heated chamber, prevents large PLA parts from warping at the edges.

High Precision and Flawless Surfaces in Every 3D Print

With a 2 mm Z screw and anti-backlash nut, each layer is placed with millimeter accuracy. The full-metal CoreXY frame, along with high-performance FOC stepper motors and high-density 1.5GT belts, ensures stable, precise, and vibration-free 3D printing. This combination delivers smooth surfaces, ultra-fine layers, and professional details, ideal for industrial 3D printing and advanced prototyping.

Safety, Efficiency, and Reliability in Industrial 3D Printing

Equipped with closed-loop temperature sensors, particle filtration, and fire-resistant materials, this printer ensures safe, controlled, and efficient operation. AI camera-based automatic error detection prevents common failures in large prints, protecting both the printer and the professional workspace.

Next-Generation Leveling Sensor

The QIDI MAX4 sensor uses the nozzle as the detector, guaranteeing zero-deviation leveling. No offsets, no guesses—just precise, real contact. Its performance is unaffected by bed surface or environmental vibrations, providing a perfect first layer and reliable plug-and-play leveling from the first use.

Initial preparation and installation: before starting up the printer, ensure that the machine is placed on a stable and level surface. Check that all chassis panels, especially the enclosed chamber door, are correctly installed to maintain homogeneous thermal conditions within the build volume. Proper assembly reduces thermal variations and warping in large parts.

Bed leveling and first layer: take advantage of the integrated automatic leveling system, which uses the nozzle as a true contact sensor to achieve a consistent first layer without misalignment or incorrect offsets. This ensures optimal first-layer adhesion, which is essential for large-format models.

Airflow control and chamber temperature: the third-generation active chamber and airflow control system help maintain the internal temperature up to ≈65 °C, which benefits the printing of technical materials and reduces warping in large parts. Keeping the doors closed during long prints helps preserve stable thermal conditions.

Material management: use specific profiles for each type of filament (PLA, ABS, PETG, TPU, PA, PC, or fiber-reinforced composites) and adjust temperatures close to the maximum supported values (up to ≈370 °C at the hotend) for demanding materials, while also ensuring appropriate layer cooling depending on the material.

Maintenance and periodic checks

Chamber and filtration cleaning: keep the build chamber and air filters (pre-filter, HEPA, and activated carbon) clean to ensure particle capture and safe operation.
Belt and guide inspection: check the tension of the 1.5GT belts and the condition of the X/Y linear guides, as well as the 2 mm Z lead screws, to ensure smooth motion and dimensional accuracy.
Filament sensor verification: ensure that the filament runout sensor and the anti-tangle system (if used with optional modules) are functioning correctly to avoid unexpected interruptions.
Firmware updates: keep the printer firmware and slicing software up to date to benefit from improvements in thermal control and profile management.
